So how big is the average penis, length and girth wise? I was talking to this guy (boyfriend?) the other day and he said his dick is so girthy he's torn a girl's vagina (as in, she started to bleed a bit because he was too big). I asked how girthy he was and he said that he's about as big as a fifty cent piece. When I asked what that meant he told me that he meant like two quarters. He said most guys are about as big as quarter and their fingers overlap some when they masterbate, and I know that's true, but a quarter is awfully small and I know that guys are bigger than that. Also, he said he couldn't even fit his dick into a toliet paper roll, and toliet paper rolls are definitely bigger than two quarters. And now I'm curious. (oh, and no, he's not lying, before you suggest that). Also, any idea on the measurements of the average female vagina?
